Title: Improved alumina-supported copper catalyst compositions for fluid-bed hydrocarbon oxyhydrochlorination.
Inventor: EDEN JAMAL SHAHAB
IPC: C07C19/045
Filed: 1980-10-14
Abstract: A catalyst composition is provided having copper chloride deposited on a fluidizable alumina support in which the support has incorporated prior to deposit of copper from 0.5 to 3.0% by weight of at least one alkali metal, alkaline earth metal or rare earth metal. Such catalyst composition is used as the fluid bed catalyst in the vapor phase reaction of ethylene, oxygen and hydrogen chloride to produce 1,2-dichloroethane. This results in improved yield and efficiency of EDC production based on ethylene and avoids operating problems caused by stickiness in the fluid bed. Incorporation of a combination of potassium and barium in the fluidizable alumina support prior to deposit of copper produces an excellent catalyst for the fluid bed ethylene oxyhydrochlorination process in which the vent gases are recycled.

Abstract: L'invention se rapporte à des composés, à des compositions et à des procédés permettant d'inactiver un virus et de détruire des cellules tumorales. Ces procédés consistent à ajouter, dans la cellule, un composé contenant un photosensibilisateur chimique et un donneur d'énergie chimique, éventuellement liés par un agent de fixation chimique. On introduit également dans la cellule des moyens permettant d'activer chimiquement le donneur d'énergie chimique, qui photoactive le photosensibilisateur chimique, lequel détruit alors la tumeur ou le virus. Le photosensibilisateur chimique , se compose de préférence d'hypéricine, de porphyrine ou d'un analogue, et le donneur d'énergie est de préférence la luciférine ou un analogue. Des procédés de synthèse de ces agents chimiques sont également décrits. En outre, le donneur d'énergie est activé par un activateur chimique. L'expression de l'activateur chimique est régulée de façon qu'il ne soit exprimé que dans les cellules tumorales ou infectées par un virus. La régulation de l'activateur chimique s'effectue par un certain nombre de procédés, y compris un procédé consistant à construire un plasmide d'expression contenant un gène codant l'activateur chimique sous le contrôle d'un promoteur qui est transactivé par la réplication du virus ou par des niveaux élevés des protéines exprimées dans les cellules tumorales.

Abstract: Lorsqu'un levier de commande (8) est actionné vers la gauche sous l'application d'une charge élevée, un capteur de pression (11) détecte une pression s'exerçant sur une soupape de commutation de direction (1), des capteurs de pression (9, 10) détectent les pressions s'exerçant sur les côtés amont et aval d'une soupape d'étranglement (4), et un capteur d'angle d'inclinaison (15) et un compteur de tours (16) détectent l'angle d'inclinaison d'un disque en nutation et le nombre de tours d'une pompe (2), les valeurs détectées de pressions, d'angle et de rotations étant introduites dans une unité de commande (12). Une unité de réglage de débit cible, pour soulever une flèche, détermine un débit cible pour soulever la flèche sur la base des signaux provenant du capteur de pression (11) et du compteur de tours (16), une unité de détection d'un débit de décharge d'une pompe détermine le débit de décharge de la pompe sur la base des signaux provenant du capteur d'angle d'inclinaison (15) et du compteur de tours (16), et une unité de détection de pression différentielle et une unité de calcul de débit de dérivation centrale déterminent un débit de dérivation centrale sur la base des signaux provenant des capteurs de pression (9, 10). Une unité de calcul d'un débit pour le cylindre de la flèche détermine un débit pour le cylindre de la flèche sur la base du débit de décharge de la pompe et du débit de dérivation centrale, et une première unité de calcul d'un déplacement cible de la pompe calcule un premier angle d'inclinaison cible υ1 de la pompe sur la base du débit différentiel entre un débit cible pour soulever la flèche et un débit du cylindre de la flèche. A ce moment, le premier angle d'inclinaison cible υ1 devient supérieur à un second angle d'inclinaison cible υ2 de la pompe pour qu'une commande négative puisse être sélectionnée par une unité de sélection de valeur maximale, et le plus petit des angles parmi le premier angle d'inclinaison cible υ1 et un angle d'inclinaison maximum υmax par commande de la puissance en chevaux est sélectionné par une unité de sélection de valeur minimale, pour qu'un courant électrique cible correspondant puisse être émis vers une soupape proportionnelle à solénoïde (13) en provenance d'une unité génératrice de signaux d'entraînement, afin d'amener un piston (6a) d'un régulateur (6) à être entraîné vers la droite, comme illustré dans la figure 4. Ainsi, le débit d'une pompe hydraulique (2) est progressivement augmenté, de sorte que des caractéristiques de mesure constamment favorables sont toujours obtenues quelle que soit l'amplitude de la charge.
